I don’t know how to do this

Step-by-step explanation:

To find the mean, or average, you add all of the numbers and divide the sum by how many there are.

In this case, you add 25,27,32,29, and 42 and then divide the sum by 5.

25+27=52+32=84+29=113+42=155.

Then divide.

155/5=31.

Step-by-step explanation:

X = 16

Answer:

x + 5y -10 = 2x

or, 5y = 2x - x + 10

or, 5y = x + 10

or, y = (x + 10)/5

Answer:

(0, - 6)

Step-by-step explanation:

The y- intercept is where the function crosses the y- axis.

This occurs when x = 0 , thus

From the table when x = 0, f(x) = - 6

The y- intercept is therefore (0, - 6 )

the cost of his monthly cable is $40.50 when you plug in 4

Answer

Step-by-step explanation:

Let's solve for z.

a(t+z)=45z+67

Step 1: Add -45z to both sides.

at+az+−45z=45z+67+−45z

at+az−45z=67

Step 2: Add -at to both sides.

at+az−45z+−at=67+−at

az−45z=−at+67

Step 3: Factor out variable z.

z(a−45)=−at+67

Answer:

d. 4^9

Step-by-step explanation:

Question:

Which expression is equivalent to 4^9/4^0?

a. 4^8

b. 4^0

c. 4^7

d. 4^9

Solution:

By definition, a number raised to the 0 power equals 1, with the possible exception of 0^0 which according to some is undefined.

Any number divided by 1 equals the number itself.

For example, 2/1 = 2; 5/1 = 5; -20/2 = -20.

4^0 = 1

Since 4^0 = 1, then when you divide 4^9 by 4^0 you are dividing 4^9 by 1, so you get 4^9.

4^9/4^0 = 4^9/1 = 4^9

Step-by-step explanation:

Let's solve for d.

y=2x2+9xfindf(10)findf(10)

Step 1: Flip the equation.

900d2f4i2n2x+2x2=y

Step 2: Add -2x^2 to both sides.

900d2f4i2n2x+2x2+−2x2=y+−2x2

900d2f4i2n2x=−2x2+y

Step 3: Divide both sides by 900f^4i^2n^2x.

The value of f(10) for function f(x) = 2x² + 9x is 290.

An algebraic expression is consists of variables, numbers with various mathematical operations,

The given function is,

f(x) = 2x² + 9x     (1)

To find the value of f(10),

Substitute x = 10,

f(10) = 2(10)² + 9(10)

f(10) = 2 x 100 + 90

f(10) = 200 + 90

f(10) = 290

The required value of f (10) is 290.

Answer:

x = 29.8

Step-by-step explanation:

x represents the unknown number

20.7 + x = 50.5

x + 20.7 - 20.7 = 50.5 - 20.7

x = 50.5 - 20.7

x = 29.8

Answer:

7.5

Step-by-step explanation:

The value of x = 7.5 when y = -30

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Given that y varies directly with x, and y = -20 and x = 5,

To determine the value of x = 7.5 when y = -30

Direct variation equations can be written as:

y = kx where "k" is a constant.

Substitute the values of y = -20 and x = 5 in the direct variation equation and solve for k:

⇒ -20 = 5k

⇒ k = -20/5

⇒ k = -4

The direct variation equation :

⇒ y = -4x

Substitute the values of y = -30 in the above equation and solve for x:

⇒ -30 = -4x

⇒ 4x = 30

⇒ x = 30/4

⇒ x = 7.5

Thus, the value ofx = 7.5 when y = -30

Answer:

19

Step-by-step explanation:

If DE bisects  <ABC, this means that <ABE = <EBC

Also <DBC+<EBC = 180

99+<EBC = 180

<EBC = 180-99

<EBC = 81

Also <ABC =<ABE+<EBC

<ABC =<EBC+<EBC

7x+29 = 81+81

7x = 162-29

7x = 133

x = 133/7

x = 19°

Hence the value of x is 19°
